“Just hanging out in scrubs with blood on my face. NOT a good look for me, but loads of fun!” wrote Minshew in an Instragram post where she showed herself in character as she prepared for surgery for the episode. “Special thanks for Dr. Audie Liametz for showing me how to perform heart surgery on #TheBlacklist. Oh and for helping me shove my crazy puffy hair under that cap!” Minshew used the hashtags “crazyhair,” “scrubs” and “theblacklist” in her post.

No word yet on when the episode will air or what specific storyline she’ll be entangled in. Stay tuned for more information as it becomes available.

The fifth season of “The Blacklist” premieres Wednesday, September 27 at 8/7c on NBC.
